    Abstract Laser frequency combs are enabling some of the most exciting scientific endeavours in the twenty-first century, ranging from the development of optical clocks to the calibration of the astronomical spectrographs used for discovering Earth-like exoplanets. Dissipative Kerr solitons generated in microresonators currently offer the prospect of attaining frequency combs in miniaturized systems by capitalizing on advances in photonic integration. Most of the applications based on soliton microcombs rely on tuning a continuous-wave laser into a longitudinal mode of a microresonator engineered to display anomalous dispersion. In this configuration, however, nonlinear physics precludes one from attaining dissipative Kerr solitons with high power conversion efficiency, with typical comb powers amounting to ~1% of the available laser power. Here we demonstrate that this fundamental limitation can be overcome by inducing a controllable frequency shift to a selected cavity resonance. Experimentally, we realize this shift using two linearly coupled anomalous-dispersion microresonators, resulting in a coherent dissipative Kerr soliton with a conversion efficiency exceeding 50% and excellent line spacing stability. We describe the soliton dynamics in this configuration and find vastly modified characteristics. By optimizing the microcomb power available on-chip, these results facilitate the practical implementation of a scalable integrated photonic architecture for energy-efficient applications.

    Abstract We demonstrate a method to generate a widely and arbitrarily tunable laser source with very narrow linewidth. By seeding a coupled-cavity microcomb with a highly coherent single-frequency laser and using injection locking of a Fabry-Perot laser to select a single output comb tone, a high power, high side mode suppression ratio output wave is obtained. The system is demonstrated across 1530 -1585 nm with a linewidth below 8 kHz, having 5 dBm output power and sidemode suppression of at least 60 dB. Prospects of extending the performance are also discussed.

  9. Article: Population genetic structure and connectivity in three montane freshwater invertebrate species (Ephemeroptera, Plecoptera, Amphipoda) with differing life cycles and dispersal capabilities

    Abstract Dispersal abilities and the resulting levels of connectivity between streams influence population structure in aquatic organisms. We investigated how different dispersal and life‐history traits affect gene flow and population structure in three aquatic invertebrate species in a central European mountain range. We used microsatellite markers and mitochondrial cytochrome oxidase I barcode data to assess small‐scale population structure and connectivity of the mayfly Baetis alpinus, the stonefly Brachyptera seticornis, and the amphipod Gammarus fossarum in seven streams within Bavarian Forest National Park, Germany. Significant population structure within the study area was detected in B. alpinus and G. fossarum, whereas B. seticornis had signatures of panmixia. In G. fossarum, that structure corresponded to stream topography, while in B. alpinus it did not. The Bavarian Forest range appears to be a contact zone for different mitochondrial lineages of B. alpinus and G. fossarum. Limited geneflow between sample sites in B. alpinus can be explained by the species’ short adult lifespans, which restricts dispersal between sites. Since imagines are able to disperse via adult flight population structure is, however, decoupled from stream topology. Longer‐lived B. seticornis is better able to maintain geneflow between sample sites. In flightless G. fossarum, population structure corresponding to stream topology can be explained by limited dispersal capabilities between streams. Dispersal ability alone is insufficient to predict or explain patterns of gene flow and connectivity for individual species, and should be examined together with life‐history traits when assessing population and community structure.

    Abstract Central Asia has been an important region connecting the different parts of Eurasia throughout history and prehistory, with large states developing in this region during the Iron Age. Archaeogenomics is a powerful addition to the zooarchaeological toolkit for understanding the relation of these societies to animals. Here, we present the genetic identification of a goitered gazelle specimen (Gazella subgutturosa) at the site Gazimulla-Tepa, in modern-day Uzbekistan, supporting hunting of the species in the region during the Iron Age. The sample was directly radiocarbon dated to 2724–2439 calBP. A phylogenetic analysis of the mitochondrial genome places the individual into the modern variation of G. subgutturosa. Our data do represent both the first ancient DNA and the first nuclear DNA sequences of this species. The lack of genomic resources available for this gazelle and related species prevented us from performing a more in-depth analysis of the nuclear sequences generated. Therefore, we are making our sequence data available to the research community to facilitate other research of this nowadays threatened species which has been subject to human hunting for several millennia across its entire range on the Asian continent.
